为了获取更准确的循环作业参数，模拟循环燃油消耗量，提出了基于运动学片段和作业特点的轮式装载机典型作业工况构建方法。定义转速扭矩面积等13个特征参数表征循环作业过程参数变化，并采用主成分分析法和模糊C均值聚类法将运动学片段聚为5类，选取每类中欧式距离最小的片段组合构成典型作业工况。结果表明：试验工况和典型工况的加速度、速度等行驶特征参数区间分布相似；基于典型工况的循环仿真油耗为0.176 L，误差为4.7％，在工程误差允许的范围内。该方法可以有效地实现轮式装载机试验数据的处理、分析以及典型作业工况的构建，对于研究装载机循环作业经济性具有一定的指导作用。

In order to obtain more precise operating parameters of typical working cycle and simulate the fuel consump-tion,a constructing method of typical working cycle for wheel loader was proposed based on kinetic sequences and oper-ating characteristics.Thirteen characteristic parameters,including speed-torque area etc.,were defined to evaluate the variation of operating parameters during working process.Meanwhile,the kinetic sequences were classified into five clusters by the adoption of the Principal Component Analysis and fuzzy C-means algorithm.Afterwards,the sequences with minimum Euclidean distance in each cluster were selected to constitute the typical working cycle.The results showed that parameters of the test condition and the typical working cycle,such as acceleration and speed,had the simi-lar distribution;fuel consumption based on the typical working cycle simulation was 0.176 L with an error of 4.7%, which was within the scope of the engineering allowable error.The proposed method could be effectively employed to process and analyze the test data of wheel loader and construct the typical working cycle,which was also greatly helpful to further study the fuel economy of loader working cycle.
